Make your first authenticated request against Meld’s Bank Linking API to confirm that your API key and provider credentials are wired up correctly.

​
Before you begin

  • You have completed Step 3: Grab your Meld API key and copied your API key.
  • You know which environment your API key belongs to (sandbox or production).

​
Steps

  1. Grab your Meld API key from the Developer tab of the Meld Dashboard.
  2. Use your API key to make a call to one of the Bank Linking API endpoints. Prefix the key with the word BASIC in the Authorization header — for example, Authorization: BASIC <your-api-key>. Header with BASIC prefix
  3. Use the correct Base URL for the environment your key belongs to:
    EnvironmentAPI Base URL
    Sandboxhttps://api-sb.meld.io
    Productionhttps://api.meld.io
    You can figure out which environment your key works for by looking at the toggle in the bottom left of the Dashboard. Dashboard environment toggle
  4. Fill out all fields marked as Required in the API Reference; the call will fail without them.
A sandbox key only works against https://api-sb.meld.io, and a production key only works against https://api.meld.io. Mixing them produces an authentication error.
